Campbell Scientific 229-L, Heat Dissipation Potential Sensor - Tested - Warranty

Description: Campbell Scientific 229-LHeat Dissipation Matric Potential Sensor OverviewThe 229 is a sensor that measures soil water potential from -10 to -2500 kPa. It requires that you connect it to either the CE4 or CE8 current excitation module. A Campbell Scientific data logger controls the current excitation module, measures the sensor, and calculates soil water matric potential. Benefits and FeaturesCompatible with most Campbell Scientific data loggersMeasures a wide range of matric potentialMeasurements not affected by salts in the soilLong lasting, with no maintenance requiredCompatible with AM16/32-series multiplexers, allowing measurement of multiple sensors Detailed Description:The 229 Water Matric Potential Sensor consists of a heating element and thermocouple placed in epoxy in a hypodermic needle, which is encased in a porous ceramic matrix. This unit comes with 20' of cable. To calculate soil water matric potential, a CE4 or CE8 current excitation module applies a 50 mA current to the 229's heating element, and the 229's thermocouple measures the temperature rise. The magnitude of the temperature rise varies according to the amount of water in the porous ceramic matrix, which changes as the surrounding soil wets and dries. Soil water matric potential is determined by applying a second-order polynomial equation to the temperature rise. Users must individually calibrate each of their 229 sensors in the soil type in which the sensors will reside. A reference temperature measurement is required for the 229’s thermocouple measurement. Options for measuring the reference temperature include:Thermistor built into the CR6, CR800, CR850, CR1000, CR3000, or CR5000 wiring panelPRT built into the wiring panel of the CR9050 or CR9051E input module for the CR9000X Measurement and Control System SpecificationsOperating Temperature Range-5° to +30°CNormal Environmental Temperature Range-40° to +70°CMeasurement Range-10 to -2500 kPaMeasurement Time30 s (typical)Thermocouple TypeCopper/constantan (type T)Heater Resistance~34 ΩResolution~1 kPa (at matric potentials < -100 kPa)Diameter1.5 cm (0.6 in.)Length6.0 cm (2.4 in.)Cable Weight~23 g/m (0.25 oz/ft)Sensor Weight10 g (0.35 oz) Shipping label printed within 8 hours of receipt of payment or the next business day.Shipping service at discretion of sellerWe are limited to the schedules and holidays hours of the carriers we use Thank you for considering our productsTake a moment to read the following to ensure a smooth experience 1.
